Conditional Expression

[calabrra]

Question: Would the AWK conditional expression:

function abs(x) {
x >= 0 ? x : -x ;
return(x) ;
}

return the absolute value or simply the input argument?

Thanks,

It would return the absolute value. However, the variable passed to the function would not be changed i.e. arguments are passed by value not by reference.
